Wearable dual-function eeg integrated bone conduction audio device

Abstract

The present invention relates to an auditory device that combines bone-conducting earbuds with integrated electroencephalography (EEG) sensors. The device utilizes bone conduction technology to transmit sound through the skull to the inner ear, allowing for clear audio perception without obstructing the ear canal. Incorporated EEG sensors are configured with spring-loaded contacts that maintain consistent skin contact to monitor brain wave activity effectively. This dual-functionality enables users to listen to audio and simultaneously track cognitive states, making the device particularly useful for applications in cognitive load monitoring and adaptive audio feedback based on the user's mental state. This innovation extends the functionality of conventional earbuds with bone-conduction mechanisms by integrating EEG technology to enhance biosensing, health monitoring, and tailored cognitive-processing feedback.
